It has always seemed to me that German brands, in general, tend to favor long legs. What sort of "weird" are your proportions?
If you are going to do local shopping, it is best just to try everything that they have.

Are you taking the bike(s) away from Europe? Better check what it costs to ship a bike, and what sort of taxes and Customs you might have to pay.

I've got massively longs and a really short torso, 6" 5' all up. In the English-speaking world a custom frame is the only real option for a good fit, but I wonder if the tall Europeans have a different range of geometries.

You are tall enough that there are few stock bikes that will fit - and maybe even fewer if your proportions are unusual. Have you checked out Zinn Cycles ? He specializes in bikes for tall people and there's also a fit calculator there: Lennard Zinn bicycle fit calculator

As for European brands, here's a few off the top of my head: Cube, Canyon, Ghost, Radon, Lapierre, Focus. Write them into Google and add "bikes", to find their websites.

check out nicolai or liteville. Nicolai builds custom size frames and liteville comes as standard with "proportion" sizes, means e.g. chainstay will grow with the size. the only real alternative I saw was specialized endure or sj 29 and had the feeling sitting ON the rear axle when the seatpost is out. this makes climbing harder.
